Meaning ❉ Sleep Stages define the distinct physiological phases our bodies cycle through during rest, each vital for the deep cellular renewal that directly impacts textured hair vitality. During these nocturnal periods, from lighter slumber to the restorative depths of NREM3 and active REM, the body engages in critical repair processes for scalp health and optimal hair follicle function. For individuals with Black and mixed-race hair, discerning these rhythms provides grounding knowledge for systematizing care, particularly through consistent nighttime regimens. This practical application, like using satin bonnets or gentle protective styles, consciously works to prevent friction and moisture loss while unconscious. Such mindful attention during slumber aids in fortifying delicate strands from their very foundation, establishing rest as an indispensable element within a comprehensive hair wellness approach.
